As a core experimental course of computer science and technology major, digital logic experiment is an important link to develop students’ computer foundation and programming ability. Aiming at the problems of high threshold, high cost and unsatisfactory experimental effect of traditional digital logic experiment, an experimental mode based on the combination of Vivado and Nexys4 DDR is proposed, and how to solve the problems of traditional digital logic experiment with this mode is analyzed. Taking the music metronome experiment as an example, this paper introduces the experimental principle, content, process and results, and reveals that this experimental mode has the characteristics of simple configuration and superior performance, and plays a great role in improving experimental efficiency and enhancing students’ enthusiasm to participate in the experiment.
